ℹ️ About AES Text Encryptor / Decryptor
The AES Text Encryptor uses the Advanced Encryption Standard (specifically the Fernet specification) to provide high-level security for your messages and secrets. Fernet is an implementation of symmetric (shared key) authenticated encryption, which ensures that an encrypted message cannot be read or modified without the correct key.
This tool uses SHA-256 to derive a cryptographically sound key from the password you provide. It's an ideal way to protect sensitive notes, passwords, or configuration details when you need to store them in an insecure location or transmit them over unencrypted channels.
📖 How to use AES Text Encryptor / Decryptor
- 1. Choose your operation: 'Encrypt' to hide text, or 'Decrypt' to reveal it.
- 2. Enter your plain text or the ciphertext provided by this tool.
- 3. Enter a strong 'Secret Key' (password). You must remember this key to decrypt the message later!
- 4. Click 'Run Tool' to perform the cryptographic operation.
❓ Frequently Asked Questions
What is 'Symmetric' encryption?
It means the same key is used for both encryption and decryption. If you lose the key, the data cannot be recovered.
How strong is this encryption?
Fernet uses AES in CBC mode with a 128-bit key and HMAC for authentication. It is considered extremely secure and is widely used in production systems.
Is my key stored on the server?
No. The operation is performed in memory and neither the key nor your clear text is ever saved to our database.
